APPARATUS FOR RECLAIMING TIN AND ZINC FROM TINNED AND ZINC SCRAP.

SPECIFICATION forming part of Letters Patent No. 657,646. datedSeptember 1 1, 1900.

Application filed May 23, 1900. Serial No. 17,768. (No model.)

To all whom, it may concern.-

Be it known that we, GEORGE BERRELL ORUIoKsHAN residing at 121 Camd enstreet, in the city of Birmingham, HERBERT ROBERT STODDARD COLEMAN,residing at 118 Sycamore road, Smethwick, in the county of Stafford, andPEROIVAL CRUIOKSHANK, residing at 121 Camden street, in the city ofBirmingham, England, subjects of the Queen of Great Britain, haveinvented new and useful Improvements in Apparatus for Reclaiming Tin andZinc from Tinned and Zinc Scrap, (for which we have made application forpatent in Great Britain under No. 7,447, hearing date April 23, 1900,)of which the following is a specification.

Our invention relates to improvements in apparatus for reclaiming tinand zinc from tinned and zinc scrap; and its objects are to provide animproved arrangement of circumferential revoluble anode-drums carriedupon a revoluble reel which is partly immersed in solution; also, toprovide mechanism whereby the circumferential anodedrums shall berevolved by frictional rolling contact upon a prepared pathway; also, toprovide such pathway with open upper part and the bearings carrying thedrums with open ends to permit of ready removal and replacing of drums.We attain these objects by the mechanism illustrated in the accompanyingdrawings, in whichh Figure 1 is a longitudinal general sectional View inelevation of the invention. Fig. 2 is a transverse sectional view of theinvention on line A B, Fig. 1. Fig. 3 is a cross-sectional view of oneof the anode-drums on line Fig. a is an enlarged detail view showingelectrical connections from end of drum to anodes.

To the sides of the vat 6 we secure bearings 7 to support shaft-journalsS. The said journals 8 are secured to the reel 9, havingflanges 10, uponwhich are carried the bearings 11. Concentric with the reel the metallicpathways 12, usually of copper, are carried by means of cross-rods 13,which are screwed at their ends to the sides of the vat, the said rodspassing through the insulating-blocks 14, which are fixed in thebrackets 12, the latter being riveted or otherwise secu red to thepathway 12. The rods 13 are also preferably insulated from the vat byblocks 15.

16 indicates the anode-drums, within which is placed the tinned or zincscrap as anodes, the said drums being provided with the usual doorwayfor access to the interior. At the ends of the drums are fixed themetallic rings 17, which frictionally roll upon the pathways 1.2, andthereby give a revolving motion to the drums. These drums may be madewith Wooden ends, while the cylindrical cover of the bodyis ofperforated metal, with metallic the journals 20 of the anode-drumssprings 21 are employed, which exert pressure thereon to insureelectrical and frictional contact. The pathway 12 continues only for agiven portion of the circle-that is, having an upper open part, so thatas the drums reach such open part they may be removed for discharge andother recharged ones replaced, and inasmuch as the speed of revolving isslow such removals and replacements may be done Without stoppage of thereel.

22 indicates the cathodes, of which more may be added as required.

It will be obvious that any of the ordinary solutions may be used in thevat, such as caustic soda, caustic potash, or the like, or solutions ofsulfuric, nitric, or hydrochloric acids. Such solutions may be heatedorother- Wise, as desired, by any suitable means. By these means the tinor zinc upon the scrap is decomposed, and, as is well known, adherenceto the cathodes is prevented by the extra strong current to thatrequired for ordinary plating, and a spongy deposit is the result, whichmay be readily removed, the majority of which would therefore beprecipitated to the bottom of the vatv as a. black" metallic powder,which would be subsequently treated in any well-known manner.

What we claim as our invention, and desire to secure by Letters Patent,is-- 1. In apparatus for reclaiming tin'or zinc from tinned or zincscrap by thev use of a chemical solution and electricity, the combi:nation of the vat 6, having suspended therein the revoluble reel 9, withflanges 10, carried in bearings 7, with the: circumferential revo= lubleperforated anode-drums 16, journaled at 11, such drums and theirinteriors being connected to the positive pole of a-battery or dynamo,and the cathode-plates 22, connected to the negative pole of a batteryor dynamo, all substantially as set forthand shown upon the drawings.

sure=springs 21, said drums having rings 17 metalli'cally andelectrically connected to anodes and of the. metallic pathway 12,insulated from tank but electrically connected to the positive pole of abattery or dynamo, with the cathode plates 22, all substantially as setforth and shown.
